Safe Scrub® ST Liquid Cleaner provides heavy-duty cleaning power for removing oil and surface soils on metals prior to finishing. This biodegradable liquid cleaner is used to emulsify oil from iron and steel parts, and then hold the oil residues in solution to prevent them from re-depositing on the parts. Designed for medium to heavy-duty soak tank cleaning of iron and steel parts, Safe Scrub ST mixes easily with water. It operates at temperatures of 120 to 180°F, effectively lifting oil residues from the metal surface and holding them in suspension. When the solution is allowed to cool, much of the emulsified oil will float to the surface, allowing removal of the oil with an oil skimmer or coalescing filter and maximizing the working life of the Safe Scrub ST cleaning solution.
The unique blend of detergents in Safe Scrub ST makes it free-rinsing in cold water. This gives it the ability to produce waterbreak-free surfaces that are receptive to subsequent coating and finishing operations. Safe Scrub ST effectively removes these types of fluids: mineral oil, grinding coolant, drawing/stamping lubes, and hydraulic oils, as well as water soluble/synthetic fluids. Supplied as a liquid concentrate, Safe Scrub ST contains biodegradable surfactants and contains no EPA regulated metals. It can be used as stand-alone cleaner after metalworking operations or as a pre-cleaner prior to metal finishing operations such as black oxide coating or phosphating. Without pollution or worker safety hazards, Safe Scrub ST maintains a high level of cleaning power while minimizing the amount of product to do the job effectively.
